Why do most inner-carbon blades have a bigger headsize nowaday?

[doppelmoral]

Hi,

I was wondering why most of the inner-carbon (limba) blades that have been released over the last years have a bigger headsize. That usually is not the case for koto outer-carbon blades.

What are the advantages of lets say a 158x152 when being compared to a 157x150 blade?

I am asking because I tried a Tibhar Zodiac Libra ZAC today, and it felt so great to play with it, I was honestly surprised. But the headsize is 159x152 I believe, ouch. The weight will be just way too high if I put heavy rubbers on a blade like that.

Cheers

Bigger head size leads to a little more flex of the blade and this favors the FH.
